Can we bridge T3200M to Boosts?

Basically, I'm trying to remove the T3200M from the picture as much as possible.

We are subscribed to 750. The T3209 modem direct test gets 350-400 on a good day. Yet testing directly from the fibre point of entry gets over 750. I saw someone suggest splitting between the fibre and the T3200M. That would remove the drag it seems to create, and keep the TVs running. I'm just not sure about what firewall and DHCP setup I can manage on the Boost...
